This invention relates to a spraying device especially adapted to beused'iu connection with a bottle or similar receptacle containingperfume, a medicinal preparation or the like.

One of the objects of the invention is to provide such a receptacle witha top having a tapered bore fitted with a stopper which is automaticallyheld therein with a predetermined pressure. Another object is to providea stopper which acts as a valve and which is rotatably adjustable torender the spraying device operable, or to cut oi the fluid outlet andthe air suppl as well as the air vent, to prevent possib e spilling orevaporation of the contents of the receptacle when the atomizer is notin use.

The above and other characteristic features of the invention will bemore specifically explained with reference to the accompanying drawings,in which Figure 1 is a central longitudinal section illustrating oneembodiment of the invention.

Figure 2 is a section taken on the line 2-2 of Figure 1.

Figure 3 is a central longitudinal section illustrating anotherembodlment of the invention.

Figure 4 is a section taken on the line 4-4 of Figure 3.

As illustrated in Figures 1 and 2 the invention is associated w1th areceptac e 5 having a metallic collar 6 in which a top 7 is removablysecured. This top is formed with an upwardly ta ered vertical bore 8which forms a seat or a correspondingly tapered stopper 9. The upper orsmaller end portion of the sto per 9 extends some distance above the topwhere it is formed with a reduced threaded end to which a head 10 issecured. The head 10 is formed with a sleeve 11 which extends downwardlysubstantially to the surface of the top 7 and is spaced from the upperportion of the stopper 9, to provide a housing for a coil spring 12which acts between the head 10 and the top 7 to urge the stopperupwardly into close fitting relation to the seat 8.

The lower end of the stopper 9 is extended downwardly into thereceptacle toform a sleeve 13 in which a liquid supply tube 14 issecured. The stopper 9 is formed with a l1qu1d passageway 15,constituting a continuation of the passageway through the tube 14 andhaving'a lateral outlet 16 which is adapted to register with a similarpassa e 17 leading through the top 7 into a lateral y disposed nozzle 18having an outlet 19.

Air pressure for inducing a flow of liquid to the nozzle 18 anddischarging it in the form of spray is supplied from an air chamberformed by securing a diaphragm 20 of rubber or the like to the head 10.An air supply passage 21 leads from this chamber through the stopper 9.This passa eway 21 has a laterally disposed outlet 22 a apted toregister with the passageway 23 through an air supply member which is inalignment with the discharge orifice 19.

When the diaphragm 20 is depressed air is forced through the passageway21 and induces a flow of liquid through the tube 14, which is dischargedfrom the orifice 19 in the form ofspray. As soon as the dia phragm 20 isreleased, the air chamber is refilled with air drawn through ports 24 inthe sleeve 11 and past a ball check valve 25 in the head 10.

The stopper 9 is also provided with an air vent passageway 27, which isadapted to register with a passageway 26 through the head 7 to admit airto the receptacle 5 and maintain normal atmospheric pressure within thereceptacle.

The stopper 9 constitutes a valve for con trolling the operation of theatomizer. In

the position shown in Figure 1 the liquid outlet passageway, the airsupply passagevway and the air vent passageway are all in open oroperative position. All of these passageways may be cut ofi, however, byrotating thevalve or stopper 9 through a small angle. Provision. is madefor limiting such rotation to an angle of approximatel 90. For thispurpose, a plug 28 is provi ed in the top 7 and has an inward extension29 projecting into an arcuate channel 30 formed in the stopper 9.

In the embodiment of the invention; shown in Figures 3 and 4, areceptacle 31 is provided with a collar 32, to which a top 33 1sthreaded or otherwise secured. The top 33 is formed with a verticalupwardly tapered bore 34, forming a seat to receive a correspondinglytapered stopper 35. A head 36 is secured to the upwarc ly projecting endof the stopper 35 and is formed with a sleeve 37 constituting a housingfor the s ring 38, which acts in the same manner as t e spring 12 inFigure 1. i

A downwardly extending sleeve 39 1s secured in the lower end of thestopper 35 and has a liquid supplyv tube 40 secured therein. The liquidfrom the receptacle 31 is supplied through the tube 40 and passageway 41and thence through a branch passageway 42 1n the stopper. This branchpassageway normally registers with a passageway 43 leading to a nozzle44 which extends laterally from the head 33 and is provided with adischarge orifice 45.

Air under pressure is supplied to the orifice 45 through a passageway 46in the top 33, which normally registers with an air supply passageway 47through the stopper 35. The air is supplied to the passageway 46 througha tube 48 having a nipple 49 secured to its outer end and adapted to beconnected with a bulb or other suitable source of air pressure.

The top 33 is also provided with an air vent passageway 50 normallyregistering with a passageway 51 leadin through the stopper 35 into theupper en of the receptacle 31.

The stopper 35 also acts as a valve which may be rotated in the samemanner as the stopper 9 in Figure 1 to cut ofl the air and liquid supplypassages as Well as the air vent passage. For limiting the rotation ofthe stopper 35, the head 36 is provided with a lug 52 projectingdownwardly into an arcuate channel 53 formed in the upper face of the to33.

rpm the foregoing description, it will be seen that the inventionprovides a receptacle with a top having a tapered seat against which thestopper is automatically held to prevent leaka a. This stopper, however,may be loosened by downward pressure, whenever it is desired to adjustthe same circumferentially. In normal position, the stopper or valvefreely opens the passageways from the liquid supply, the air pressuresupply, and the air which is supplied to the receptacle to maintainatmospheric pressure therein. All these passageways, however, may be cutoff simultaneously by a partial rotation of the valve or stopper.

While I have described specifically the various features of theinvention as embodied herein, it will be understood that the inventionis not limited thereto but includes all such modifications as may fallwithin the scope of the appended claims.
